OS SDK and iOS 4.1 beta are now available from the iPhone Dev Center.

So what’s new in iOS 4:

• Multitasking

  • Background audio
  • Voice over IP
  • Background location
  • Push notifications
  • Local notifications
  • Task finishing
  • Fast app switching

• iAd

There will be better Ad service and display. I just wonder if this will hit Ad Mob. Anyway, most important to developer Apple will sell and serve the ads, and developers will receive 60 percent of iAd revenue.

• Game Center

Apple is going very fast to social network with game center. Basically connect the gamer together, provide a center platform so that information can be exchanged.

iOS SDK 4 contains over 1500 new APIs. I have to say the Apple are listing to their customer and everything just getting better and smarted after each release.

We have received our iPad and the experience is great. A lot of people are saying that iPad is just a big iPhone. And yes, it is exactly what I need. I am using iPhone for: email, banking, read news, play game, …and I need that big screen that iPads have and of cos there are so manything you can do on iPad that you are not able to do on iPhone
